An assassin has critically wounded Captain America, poisoning him with an unknown form of radiation. Doctor Blake is performing surgery on his fallen friend, inserting counter-radiation capsules inside of Cap.

While Blake performs the surgery, the Avengers stand watch in the hospital. Iron Man has become concerned that it is too easy to form a connection between Doctor Blake and Thor, so he has created a lifelike android duplicate of Thor, known as a “Life Model Decoy” or “LMD” for short. The Android poses as Thor to cover for Blake.

The Assassin and her agents disable the Avengers guarding the operation, including the LMD. The Assassin discovers that “Thor” is a robot, confirming what her research has lead her to suspect: Thor and Blake are one and the same. She had poisoned Captain America in order to flush out the elusive doctor, who is much more susceptible to bullets than his godly alter ego.

However, the unconscious Avengers recover, causing the Assassin to flee, only to be accidentally killed by her own men.
